My 16 month old has been having flat non blanching rashes for almost 20 days now. It started from her lower legs and slowly spread to full legs, arms, face and few on the trunk. She doesn't have any other symptoms and the rashes don't itch. She is her usual self otherwise. I am sharing some pictures for reference. Have shown these to our regular paediatrician twice ( last time 10 days back) who thinks these could be atypical hfmd. My worry is it's not going away. Very few spots I have noticed fading But new ones are still appearing. Please suggest if a blood test is required
